Cell surfaces display a wide array of molecules that confer identity. While flow cytometry and cluster of differentiation (CD) markers have revolutionized cell characterization and purification, functionally heterogeneous cellular subtypes remain unresolvable by the CD marker system alone. Using hematopoietic lineages as a paradigm, we leverage the extraordinary molecular diversity of heparan sulfate (HS) glycans to establish cellular “glycotypes” by utilizing a panel of anti-HS single-chain variable fragment antibodies (scFvs). Prospective sorting with anti-HS scFvs identifies functionally distinct glycotypes within heterogeneous pools of mouse and human hematopoietic progenitor cells and enables further stratification of immunophenotypically pure megakaryocyte–erythrocyte progenitors. This stratification correlates with expression of a heptad of HS-related genes that is reflective of the HS epitope recognized by specific anti-HS scFvs. While we show that HS glycotyping provides an orthogonal set of tools for resolution of hematopoietic lineages, we anticipate broad utility of this approach in defining and isolating novel, viable cell types across diverse tissues and species.
Innatus immunis: Evolving paradigm of adaptive NK cells
Authors: Mohamed Khalil, Subramaniam Malarkannan
Journal: The Journal of Experimental Medicine (2022)

The mechanisms that govern the development of adaptive-like NK cells are elusive. Shemesh et al. (2022. J. Exp. Med.https://doi.org/10.1084/jem.20220551) report that the development of FcRγ−/low adaptive-like NK cells requires reduced mTOR activity and depends on TGF-β or IFN-α. These findings provide exciting new molecular blueprints explaining the development and functions of adaptive-like NK cells.

ASXL1/2 mutations and myeloid malignancies
Authors: Edward A. Medina, Caroline R. Delma, Feng-Chun Yang
Journal: Journal of Hematology & Oncology (2022)

Myeloid malignancies develop through the accumulation of genetic and epigenetic alterations that dysregulate hematopoietic stem cell (HSC) self-renewal, stimulate HSC proliferation and result in differentiation defects. The polycomb group (PcG) and trithorax group (TrxG) of epigenetic regulators act antagonistically to regulate the expression of genes key to stem cell functions. The genes encoding these proteins, and the proteins that interact with them or affect their occupancy at chromatin, are frequently mutated in myeloid malignancies. PcG and TrxG proteins are regulated by Enhancers of Trithorax and Polycomb (ETP) proteins. ASXL1 and ASXL2 are ETP proteins that assemble chromatin modification complexes and transcription factors. ASXL1 mutations frequently occur in myeloid malignancies and are associated with a poor prognosis, whereas ASXL2 mutations frequently occur in AML with t(8;21)/RUNX1-RUNX1T1 and less frequently in other subtypes of myeloid malignancies. Herein, we review the role of ASXL1 and ASXL2 in normal and malignant hematopoiesis by summarizing the findings of mouse model systems and discussing their underlying molecular mechanisms.

Authors: Ian J. Stewart, Megan E. Amuan, Chen-Pin Wang, Eamonn Kennedy, Kimbra Kenney, J. Kent Werner, Kathleen F. Carlson, David F. Tate, Terri K. Pogoda, Clara E. Dismuke-Greer, W. Shea Wright, Elisabeth A. Wilde, Mary Jo Pugh
Journal: JAMA Neurology (2022)

Traumatic brain injury (TBI) was common among US service members deployed to Iraq and Afghanistan. Although there is some evidence to suggest that TBI increases the risk of cardiovascular disease (CVD), prior reports were predominantly limited to cerebrovascular outcomes. The potential association of TBI with CVD has not been comprehensively examined in post-9/11-era veterans.To determine the association between TBI and subsequent CVD in post-9/11-era veterans.This was a retrospective cohort study conducted from October 1, 1999, to September 30, 2016. Participants were followed up until December 31, 2018. Included in the study were administrative data from the US Department of Veterans Affairs and the Department of Defense from the Long-term Impact of Military-Relevant Brain Injury Consortium-Chronic Effects of Neurotrauma Consortium. Participants were excluded if dates did not overlap with the study period. Data analysis was conducted between November 22, 2021, and June 28, 2022.History of TBI as measured by diagnosis in health care records.Composite end point of CVD: coronary artery disease, stroke, peripheral artery disease, and cardiovascular death.Of the 2 530 875 veterans from the consortium, after exclusions, a total of 1 559 928 veterans were included in the analysis. A total of 301 169 veterans (19.3%; median [IQR] age, 27 [23-34] years; 265 217 male participants [88.1]) with a TBI history and 1 258 759 veterans (80.7%; median [IQR] age, 29 [24-39] years; 1 012 159 male participants [80.4%]) without a TBI history were included for analysis. Participants were predominately young (1 058 054 [67.8%] <35 years at index date) and male (1 277 376 [81.9%]). Compared with participants without a history of TBI, diagnoses of mild TBI (hazard ratio [HR], 1.62; 95% CI, 1.58-1.66; P < .001), moderate to severe TBI (HR, 2.63; 95% CI, 2.51-2.76; P < .001), and penetrating TBI (HR, 4.60; 95% CI, 4.26-4.96; P < .001) were associated with CVD in adjusted models. In analyses of secondary outcomes, all severities of TBI were associated with the individual components of the composite outcome except penetrating TBI and CVD death.Results of this cohort study suggest that US veterans with a TBI history were more likely to develop CVD compared with veterans without a TBI history. Given the relatively young age of the cohort, these results suggest that there may be an increased burden of CVD as these veterans age and develop other CVD risk factors. Future studies are needed to determine if the increased risk associated with TBI is modifiable.

Association of Daily Step Count and Intensity With Incident Dementia in 78 430 Adults Living in the UK
Authors: Borja del Pozo Cruz, Matthew Ahmadi, Sharon L. Naismith, Emmanuel Stamatakis
Journal: JAMA Neurology (2022)

Importance Step-based recommendations may be appropriate for dementia-prevention guidelines. However, the association of step count and intensity with dementia incidence is unknown. Objective To examine the dose-response association between daily step count and intensity and incidence of all-cause dementia among adults in the UK. Design, Setting, and Participants UK Biobank prospective population-based cohort study (February 2013 to December 2015) with 6.9 years of follow-up (data analysis conducted May 2022). A total of 78 430 of 103 684 eligible adults aged 40 to 79 years with valid wrist accelerometer data were included. Registry-based dementia was ascertained through October 2021. Exposures Accelerometer-derived daily step count, incidental steps (less than 40 steps per minute), purposeful steps (40 steps per minute or more), and peak 30-minute cadence (ie, mean steps per minute recorded for the 30 highest, not necessarily consecutive, minutes in a day). Main Outcomes and Measures Incident dementia (fatal and nonfatal), obtained through linkage with inpatient hospitalization or primary care records or recorded as the underlying or contributory cause of death in death registers. Spline Cox regressions were used to assess dose-response associations. Results The study monitored 78 430 adults (mean [SD] age, 61.1 [7.9] years; 35 040 [44.7%] male and 43 390 [55.3%] female; 881 [1.1%] were Asian, 641 [0.8%] were Black, 427 [0.5%] were of mixed race, 75 852 [96.7%] were White, and 629 [0.8%] were of another, unspecified race) over a median (IQR) follow-up of 6.9 (6.4-7.5) years, 866 of whom developed dementia (mean [SD] age, 68.3 [5.6] years; 480 [55.4%] male and 386 [54.6%] female; 5 [0.6%] Asian, 6 [0.7%] Black, 4 [0.4%] mixed race, 821 [97.6%] White, and 6 [0.7%] other). Analyses revealed nonlinear associations between daily steps. The optimal dose (ie, exposure value at which the maximum risk reduction was observed) was 9826 steps (hazard ratio [HR], 0.49; 95% CI, 0.39-0.62) and the minimal dose (ie, exposure value at which the risk reduction was 50% of the observed maximum risk reduction) was 3826 steps (HR, 0.75; 95% CI, 0.67-0.83). The incidental cadence optimal dose was 3677 steps (HR, 0.58; 95% CI, 0.44-0.72); purposeful cadence optimal dose was 6315 steps (HR, 0.43; 95% CI, 0.32-0.58); and peak 30-minute cadence optimal dose was 112 steps per minute (HR, 0.38; 95% CI, 0.24-0.60). Conclusions and Relevance In this cohort study, a higher number of steps was associated with lower risk of all-cause dementia. The findings suggest that a dose of just under 10 000 steps per day may be optimally associated with a lower risk of dementia. Steps performed at higher intensity resulted in stronger associations.
Diagnosis and Treatment of Myelodysplastic Syndromes
Authors: Mikkael A. Sekeres, Justin Taylor
Journal: JAMA (2022)

<h3>Importance</h3> Myelodysplastic neoplasms (MDS), formerly known as myelodysplastic syndromes, are clonal hematopoietic malignancies that cause morphologic bone marrow dysplasia along with anemia, neutropenia, or thrombocytopenia. MDS are associated with an increased risk of acute myeloid leukemia (AML). The yearly incidence of MDS is approximately 4 per 100 000 people in the United States and is higher among patients with advanced age. <h3>Observations</h3> MDS are characterized by reduced numbers of peripheral blood cells, an increased risk of acute myeloid leukemia transformation, and reduced survival. The median age at diagnosis is approximately 70 years, and the yearly incidence rate increases to 25 per 100 000 in people aged 65 years and older. Risk factors associated with MDS include older age and prior exposures to toxins such as chemotherapy or radiation therapy. MDS are more common in men compared with women (with yearly incidence rates of approximately 5.4 vs 2.9 per 100 000). MDS typically has an insidious presentation, consisting of signs and symptoms associated with anemia, thrombocytopenia, and neutropenia. MDS can be categorized into subtypes that are associated with lower or higher risk for acute myeloid leukemia transformation and that help with therapy selection. Patients with lower-risk MDS have a median survival of approximately 3 to 10 years, whereas patients with higher-risk disease have a median survival of less than 3 years. Therapy for lower-risk MDS is selected based on whether the primary clinical characteristic is anemia, thrombocytopenia, or neutropenia. Management focuses on treating symptoms and reducing the number of required transfusions in patients with low-risk disease. For patients with lower-risk MDS, erythropoiesis stimulating agents, such as recombinant humanized erythropoietin or the longer-acting erythropoietin, darbepoetin alfa, can improve anemia in 15% to 40% of patients for a median of 8 to 23 months. For those with higher-risk MDS, hypomethylating agents such as azacitidine, decitabine, or decitabine/cedazuridine are first-line therapy. Hematopoietic cell transplantation is considered for higher-risk patients and represents the only potential cure. <h3>Conclusions and Relevance</h3> MDS are diagnosed in approximately 4 per 100 000 people in the United States and are associated with a 5-year survival rate of approximately 37%. Treatments are tailored to the patient’s disease characteristics and comorbidities and range from supportive care with or without erythropoiesis-stimulating agents for patients with low-risk MDS to hypomethylating agents, such as azacitidine or decitabine, for patients with higher-risk MDS. Hematopoietic cell transplantation is potentially curative and should be considered for patients with higher-risk MDS at the time of diagnosis.
